Aultderg Burn, 2.5 km. south of Fochabers, Morayshire. Earth pillars of gravel and till overlying Old Red Sandstone conglomerate. Rapid fluvial erosion has cut deep gullies in sand and gravel, which overlies till, which in turn overlies conglomerate. Tussocks preserve certain areas from erosion. When all vegetation has been removed, the pillars are protected from erosion by large cobbles in the gravel. The earth pillar in the photo appears to be formed mainly of till which, due to the nature of the bedrock, is very stony and has little clay matrix.
